+\func{}{wxBitmap}{\param{const char}{ bits[]}, \param{int}{ width}, \param{int}{ height}\\
+ \param{int}{ depth = 1}}
Creates a bitmap from an array of bits.
-\func{}{wxBitmap}{\param{const int}{ width}, \param{const int}{ height}, \param{const int}{ depth = -1}}
+You should only use this function for monochrome bitmaps ({\it depth} 1) in
+portable programs: in this case the {\it bits} parameter should contain an XBM
+image.
-Creates a new bitmap.
+For other bit depths, the behaviour is platform dependent: under Windows, the
+data is passed without any changes to the underlying {\tt CreateBitmap()} API.
+Under other platforms, only monochrome bitmaps may be created using this
+constructor and \helpref{wxImage}{wximage} should be used for creating colour
+bitmaps from static data.
-\func{}{wxBitmap}{\param{const char**}{ bits}}
+\func{}{wxBitmap}{\param{int}{ width}, \param{int}{ height}, \param{int}{ depth = -1}}
+
+Creates a new bitmap. A depth of -1 indicates the depth of the current screen
+or visual. Some platforms only support 1 for monochrome and -1 for the current
+colour setting. Beginning with version 2.5.4 of wxWidgets a depth of 32 including
+an alpha channel is supported under MSW, Mac and GTK+.
+
+\func{}{wxBitmap}{\param{const char* const*}{ bits}}
Creates a bitmap from XPM data.
-\func{}{wxBitmap}{\param{const wxString\& }{name}, \param{const long}{ type}}
+\func{}{wxBitmap}{\param{const wxString\& }{name}, \param{long}{ type}}
Loads a bitmap from a file or resource.
+\func{}{wxBitmap}{\param{const wxImage\&}{ img}, \param{int}{ depth = -1}}
+
+Creates bitmap object from the image. This has to be done
+to actually display an image as you cannot draw an image directly on a window.
+The resulting bitmap will use the provided colour depth (or that of the
+current system if depth is -1) which entails that a colour reduction has
+to take place.
+
+When in 8-bit mode (PseudoColour mode), the GTK port will use a color cube created
+on program start-up to look up colors. This ensures a very fast conversion, but
+the image quality won't be perfect (and could be better for photo images using more
+sophisticated dithering algorithms).
+
+On Windows, if there is a palette present (set with SetPalette), it will be used when
+creating the wxBitmap (most useful in 8-bit display mode). On other platforms,
+the palette is currently ignored.
